Hi Greg;
Sorry for the delay, the real world called for some attention.
I looked up the tube and it shouldn't present any problems, but you will
need to make some choices....
The QTC mounts I make are base on a 12 pin connector. Your tubes would
require at least a 16 pin. This is no problem as I would have needed a new
adapter for any new footprint.
This will require more driver chips and a code change to a longer data
strea, trivial
We will need to work out the display characters (more personal taste) as is
see a .gif uses different segments than I used for my LED clock, trivial
ROM change
My base CPU will work with only firmware changes, the question to you is
about the tube carrier and what you want it to look like.
Assume 6 tubes for a H/M/S clock
Assume tubes are spaced TT..TT..TT (any colon between?)
Assume Clock will display with "character numbers" for clock, What for
date? JUN 20 19 format or something else.
Do you want int/ext temp/humidity? If so, what will be the display format?
You have full alpha ability, anything else to display ("EAT AT JOES")?
Will you want pimp lights (base illumination)?
Anything else?
We can go with a modified small display PCB which is a little under 2"
depth, width determined by tube spacing or with a standard display hub with
3 20 pin ribbon cables to 3 display clusters. Possibly wasier to build into
a case, your call
If we get started, I should send you a clock with either a small display or
a cluster display for you to get a feeling about. On your end, I will need
the loan 1 or preferably 2 tubes for development
Also, I am an electrical guy, anytime I get case work done, it is a friend
or contracted to small machine shops. I can't help with a case but will
gladly work with and modify designs for whoever you have doing the case.
Anything I missed?
